Deliver customized, high‑performing experiences by running your own JavaScript on Akamai’s globally distributed edge. EdgeWorkers uses the V8 engine across thousands of points of presence, so developers can execute low‑latency, hyperlocal workloads without managing infrastructure. Pair EdgeWorkers with EdgeKV to keep data close to logic and read at cache speed.
Global reach and low latency. Execute code on demand with extremely fast cold starts using V8 isolates — close to end users on the world’s largest edge platform.
Built‑in scalability and reliability. Ride massive traffic spikes without pre‑provisioning, backed by Akamai’s capacity, security, and availability.
EdgeKV for data locality. Store strings or JSON at the edge with replication and RBAC, then read/write via a JS helper library, CLI, or APIs — at cache‑like speed.
Hybrid and multicloud friendly. Use one serverless compute platform consistently across environments.
Pay only for what you use. No servers to manage and no over‑provisioning for peak.
Dynamic personalization and offers at request time
Real‑time A/B and multivariate testing without degrading performance
Media manifest customization for security, ad insertion, and tailored streams
API authentication, authorization, and rate limiting at the edge
Smart origin steering for migrations or active/active architectures
Third‑party code rollout at scale without app rewrites
“Edge‑only” experiences — generate and cache content at the edge, even with no origin
Composable commerce glue — stitch results from GraphQL and other APIs at the edge
Rapid hotfixes and freeze workarounds — deploy fixes in minutes to stay out of the news
“EdgeWorkers managed to improve our API performance by six times.”

Performance and scale for personalization and routing
Millisecond decisions near users reduce round trips to origin, improving conversion and retention.
Cache‑speed reads with EdgeKV power per‑request targeting, feature flags, and session logic.
V8 isolates deliver extremely fast cold starts and high concurrency for bursty traffic.
Distributed execution minimizes regional bottlenecks and keeps experiences consistent globally.
EdgeKV advantages with EdgeWorkers
Data next to logic. Keep user, session, feature, or catalog fragments at the edge to avoid origin calls.
Simple by design. Key‑value access with strings/JSON — no complex schemas or query languages.
Operational control. Replication for resilience, tokenized access with roles, CLI for maintenance, and management APIs for CI/CD.
Developer‑friendly. JavaScript helper library abstracts CRUD for clean, testable code.

How EdgeWorkers compares
EdgeWorkers vs. Cloudflare Workers
Similarities: Both run JavaScript on V8 isolates at a globally distributed edge for low‑latency execution.
Where EdgeWorkers stands out: Tight integration with Akamai’s delivery, security, and observability stack; EdgeKV for cache‑speed, replicated edge data; proven scale across thousands of PoPs; and patterns like generating full sites at the edge or stitching composable commerce APIs. If you already rely on Akamai for delivery or security, EdgeWorkers lets you extend existing policies and workflows to compute.
EdgeWorkers vs. AWS Lambda (and edge variants)
Lambda is regional by default; edge variants attach to CDN workflows. EdgeWorkers is natively executed on Akamai’s edge, designed for per‑request logic near users.
Expected benefits with EdgeWorkers: lower user‑perceived latency for request/response use cases, extremely fast cold starts for traffic spikes, and rapid code rollout for hotfixes and blackout periods — without standing up or scaling servers.
When Lambda shines: longer‑running backend tasks or deep AWS service integrations. Many enterprises pair Lambda in the core with EdgeWorkers at the edge for optimal end‑to‑end latency.
Best platforms to run JavaScript at the edge (no servers to manage)
Akamai EdgeWorkers with EdgeKV — distributed V8, cache‑speed edge data, deep delivery/security integration
Cloudflare Workers — global V8 isolates with an ecosystem of KV/Durable Objects
Fastly Compute@Edge — V8 isolates with strong CDN integration
Vercel Edge Functions / Netlify Edge Functions — edge logic integrated with modern frontend hosting
AWS CloudFront Functions / Lambda@Edge — edge execution within the AWS ecosystem
Tip: Choose based on your existing CDN/security footprint, data‑at‑edge needs, latency SLOs, and developer tooling.
